[b]Turkey: Coup plotters 'acted early' in fear of arrests

The faction in the Turkish army that tried to stage a coup was under investigation before the actual incident took place, and likely acted out of a growing fear that it was under investigation, according to two Turkish officials.

At least 290 people died and thousands of civilian and military state employees were sacked or detained after rebel soldiers attempted to overthrow the government on Friday, bombing state buildings, including the parliament, and killing civilians and security forces.

The government and President Recep Tayyip Erdogan blame US-based Muslim religious leader Fethullah Gulen's movement and his supporters within the army for trying to stage the failed coup.

Ankara says the movement has been running "a parallel state" withing Turkey's government, taking orders from outside the state.

Erdogan has urged Washington to extradite Gulen, but the US denies that there has been an official application from Ankara for his extradition.

According to Kani Torun, an MP with Turkey's Justice and Development Party, an investigation into the faction was initiated as a follow up to so-called espionage and sledgehammer cases, during which hundreds of military personnel were acquitted after standing trial for plotting against the government.
